Capacitive touch screen channel mapping matrix data acquisition method

The invention discloses a method for acquiring channel mapping matrix data of a capacitive touch screen. The method comprises the following steps: acquiring original channel data of the capacitive touch screen before channel mapping and a first original value of an original channel; calculating a first area proportion of each original channel on the capacitive touch screen; obtaining mapping channel data of the capacitive touch screen after channel mapping; calculating a second area proportion of each mapping channel corresponding to each original channel on the capacitive touch screen after channel mapping; calculating a proportion weight according to the first area proportion and the second area proportion; calculating a second original value corresponding to each mapping channel according to the first original value and the proportion weight; and calculating matrix data of the capacitive touch screen after channel mapping according to the second original value. According to the invention, any channel mappi
